Kate Hudson celebrated her 37th birthday today, and has never looked better, thanks to an alkaline diet, yoga workouts and cardio exercise.
Kate, who showed off her sexy bikini body on Instagram, has maintained her 70-pound weight loss since giving birth to her second child in 2011.
Kate’s weight loss secrets were a low-carb alkaline diet, yoga, and Brazilian Butt Lift workouts, as Celebrity Health Fitness has reported.
Hudson, a longtime fitness fanatic, said consistency is the key to her hot bikini body. “People think you need two hours a day to do it, and that’s bullsh*t,” said Kate. “If you work out 20 minutes a day in some way, you’re going to see changes.”

Kate is a proponent of the Alkaline Diet, whose other celebrity fans are Kelly Ripa and Elle Macpherson.
“Because I want to be as healthy as possible, I eat alkaline,” said Hudson. “It’s no dairy, it’s no wheat, it’s gluten-free, no meat and no sugar.”
The 5-foot-6 Hudson, who once weighed 184 pounds, said losing the baby weight was excruciating. Kate exercised up to 6 hours a day to slim down, Examiner reported.
While she no longer works out for hours at a time, Kate exercises daily because it makes her feel good.

Hudson’s bikini workout regimen these days includes running sprints, weightlifting, cardio exercise and Brazilian Butt Lift. “I love Brazilian Butt Lift, it’s like a DVD,” she said.
Kate, who loves to eat, said diet is critical for maintaining her flat abs and 70-pound weight loss, and said the Alkaline Diet is perfect for her.
“When you start to become more alkaline, it’s just basically healthier,” said Hudson. “Everything digests better, your blood is [at a proper pH balance].”

On the Alkaline Diet, people are often able to eat even more than they usually do.
The theory behind the Alkaline Diet is that eating a diet high in alkaline-producing foods will minimize acid buildup in our bodies (which fuels inflammation, aging and weight gain).
When you ingest too many acidic foods, your pH levels get disrupted, causing weight gain and disease, said Dr. Stephan Domenig, author of The Alkaline Cure.

The alkaline diet can transform your body and mind so you can embrace total health and well-being, said Marta Tuchowska, author of How to Lose Massive Weight with the Alkaline Diet.
Kate Hudson is now fitter, healthier and happier than ever. “I really do feel very lucky,” she said. “I’ve had my kids and my relationships. I’ve set my life down. I’m at peace, and that’s a really nice feeling.”
